Residents of Los Angeles are facing significant health risks as three wildfires rage on in the greater LA area, leading to the destruction of homes and the issuance of a smoke advisory from the Los Angeles Department of Public Health. To provide context, an Air Quality Index (AQI) of 100 is designated as hazardous for vulnerable groups, and levels exceeding 150 can adversely affect everyone, as per guidelines from the Environmental Protection Agency (EPA). Currently, the AQI readings in many parts of the LA metro area are alarmingly over 300.
Exposure to air that exceeds safe levels can trigger a defensive response in the lungs and nasal passages. This initial reaction may include coughing and sneezing, which can progress to increased mucus production and inflammation over time, according to Dr. Tania Elliott, spokesperson for the American College of Allergy, Asthma and Immunology.
While mild irritation may be the least of the concerns, prolonged exposure poses serious long-term health threats, emphasizing the importance of taking proactive safety measures. Below are essential insights regarding air quality and protective strategies.
Understanding Air Quality Concerns
It’s crucial to recognize the two primary categories of air pollutants. The first is ground-level ozone, which is a toxic pollutant formed when nitrogen oxides and volatile organic compounds react with heat and sunlight. Sources of these chemicals include vehicle emissions, industrial processes, gasoline fumes, and certain cleaning products, according to the National Oceanic and Atmospheric Administration (NOAA).
The second type of pollution is particulate matter, encompassing substances such as dust, soot, and smoke, emitted from vehicles, factories, and, of course, wildfires. While the respiratory system can usually filter out these airborne particles, elevated concentrations can become overwhelming. “At certain levels, these pollutants can surpass the body’s natural defenses,” explains Dr. Raymond Casciari, a pulmonologist in Orange, California.
High levels of air pollution create dangers for everyone, as even brief exposure can lead to breathing difficulties and may contribute to chronic respiratory diseases. However, individuals with existing lung conditions such as asthma or chronic obstructive pulmonary disease (COPD) face heightened risks. “Exposure to harmful air pollutants can worsen underlying lung diseases, leading to symptoms like coughing, shortness of breath, and wheezing,” notes Dr. Jonathan Parsons, director at The Ohio State University Wexner Medical Center.
Guidelines for Safety During Poor Air Quality
During times of poor air quality, individuals may feel a lack of control over their health. Nevertheless, there are actions one can take to help mitigate risks.
1. Stay informed.
It is essential to monitor local air quality levels. Websites like AirNow.gov offer comprehensive air quality reports nationwide, utilizing a color-coded system to indicate levels of safety (green indicates good quality, while red means hazardous). The site also provides forecasts to help plan for days when pollution may increase.
